You know, finding a vibrant and recognizable sound among much fierce competition from the likes of Opeth, Katatonia or Green Carnation in the progressive metal scene is, to some people, beyond the bounds of possibility. Progressive metal is probably the only metal genre that, even after being combined with different elements, never loses its identity. Take Ark's Burn The Sun and Opeth's Blackwater Park for example, they are two stupendous masterpieces flagged as progressive but fall in different categories, and yet the enthralling complex song structure that pretty much defines progressive metal is brilliantly instilled in both.
